In the first reaction, Gold (Au) gets 3 electrons and became Gold. In the second reaction, Iodine (I) loses 2 electrons and became Iodine.

When the atom loses the election then it is called a cation and when it gains the electron is called an anion.

Two reactions are given.

First reaction;

Au³⁺ + 3e⁻ ⇒ Au

In the first reaction, Gold (Au) gets 3 electrons and became Gold.

Second reaction;

2I⁻ ⇒ I₂ + 2e⁻

In the second reaction, Iodine (I) loses 2 electrons and became Iodine.

More about the cation and the anion link is given below.

Answer:

angle 1 = 68 degree

angle 2 = 55 degree

angle 3 = 57 degree

angle 4 = 57 degree

angle x = 123 degree

Answer: 6.6

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

the measure of an inscribed angle is half the measure of its intercepted arc, so

arc DE = 2 × ∠ DFE = 2 × 18° = 36°

DF is a diameter of the circle , then

arc DEF = 180° , then

arc EF = 180° - 36° = 144°

Now

mEF and m DE lies in one line hence supplementary

mEF:-

The equation of the line passing through the point (-1, 1) and (0, 10)  is y = 9x + 10

A linear function is in the form:

y = mx + b

Where y, x are variables, m is the rate of change and b is the y intercept.

From the table, using the point (-1, 1) and (0, 10) ,hence:

[tex]y-1=\frac{10-1}{0-(-1)} (x-(-1))\\\\y=9x+10[/tex]

The equation of the line passing through the point (-1, 1) and (0, 10)  is y = 9x + 10

Answer:

4 pack

Step-by-step explanation:

£2.04 ÷ 4 is 51p. If we divide £2.04 by 4 (we are dividing it by 4 because that is the amount of rolls) it gives us how much 1 roll is in that pack. 1 roll = 51p in the 4 pack.

£4.68 ÷ 9 is 52p. If we divide £4.68 by 9 (we are dividing it by 9 because that is the amount of rolls) it gives how much 1 roll is in that pack. 1 roll = 52p.

Therefore, the 4 pack is cheaper as 1 roll costs less. The 4 pack is better value.

Answer: a (x+3)^2=15

Answer:

-3

Step-by-step explanation:

assuming that the x is the same in both problems, to get 2 as your solution, in the first problem x÷8 would have to equal 0. so x would have to be 0. sense 0 + 2 equals 2.

Then plug 0 into x in the first equation to check your work, and if it equals the answer givin to you (2), plug 0 into the equation you are trying to solve.

so 9×0 is 0, then 0 - 3 would give you -3

thanks for coming to my ted talk, lmk if it helped!! :)

Answer:

123

Step-by-step explanation:

(2+x)/8 = 2

Multiply both sides by 8 to eliminate the fraction

2+x =16

x=14

        9x14 = 126

    126-3 = 123

Answer:

2 seconds

Step-by-step explanation:

This means the height, and thus h(t), is equal to zero.

0=-16t^2 + 16t + 32

0= t^2 - t - 2 (divide both sides by -16)

0 = (t-2)(t+1) [factor]

t = -1, 2 [set each factor equal to zero]

But as time cannot negative, take t=2, giving us 2 seconds.

Answer:

So multiplying decimal and whole number means it will always equal as a decimal. But multiplying decimal with decimal means could equal whole or decimal number

Step-by-step explanation:

Answer:

Essentially, they are same thing

Step-by-step explanation:

For example, 3 x 0.4 = 1.2

0.3 x 0.4 = 0.12

The only thing that changes are the amount of numbers behind the decimal. So when multiplying decimals, you just multiply like normal (3 x 4 = 12), then you count the amount of decimal spaces (two) and you take the number (12) and move the decimal place to the left twice. 12.0 would go to 1.2 if multiplying by a tenth.

Answer:

The Enlightenment was a seventeenth- and eighteenth-century intellectual movement that aimed to better society via fact-based reasoning and investigation. The Enlightenment introduced secular ideas to Europe, changing people's perceptions of problems like liberty, equality, and individual rights. Today, such ideas are the bedrock of the world's most powerful democracies.

Step-by-step explanation:

two ideas that emerged from the Enlightenment:

Intellectuals like Jean-Jacques Rousseau and John Locke introduced the idea that no monarch should have absolute authority. Both claimed that leaders' authority came from the people, not from God. And, according to Locke, if people disagreed with their leader, they had the right to have their government replaced with one that honored their rights.

Pre-Enlightenment Equality Powerful individuals known as the nobility had exclusive privileges to buy land, avoid taxes, and hold privileged jobs across Europe, while the lowest elements of society battled to make ends meet. The Enlightenment questioned this system, with intellectuals such as John Locke arguing that all men are created equal and that no one should be born with more power than another.
